Specification of Letters Patent.

Patented March 17, 1908.

Application filed July 8, 1907. Serial No. aaaeao.

To all chom it may concern:

. Be it known that 1, Columns GIBBS, a citi- Zen of the United States, residing in'borough of Bronx, city of'New York, in the county of New York-and State of New York, have invented certain new and useful improvements inTypc-Writing Machines, of which the'following is a specification.

This invention relates to the type-bars and hangers of writing machines, and articularly tothat class of hangers disc oscd in United States Letters Patent No. 854,484, in

which the hanger is in the form of a thin plate, and is fastened in a radiating groove.

" pally ty -ba-r.

locfied in position.

The present improvements relate princithe hanger, and one of the objects thereo is to facilitate detachment and attachment of the hangers independently of one another. To this end, 1 provide the hangers with individual looks or fasteningi devices, which in this instance are in the form of cams placed in the hanger slots in the segment, and manipulate to lock and unlock the hangers; eac 1 of the latter being preferably provided with two seats against both of which it is pressed by the locking device.

In the accom anying drawings, Figure 1 is a sectional sic e elevation of a front strike machine of the Underwood class showing my improvements applied thereto. 2 is a sectional front perspective view of a type-bar segment showing a hanger and In Figs. 1 and-2 the hanger is Fig. 3 is a fra mentary view similar to Fig. 1, but showing the hanger released. Fig.4 is an elevation of the hanger and type-bar. Fi '5 is a sectional fragmentary view of t e segment. Fig. 6 is a fragmentary view similar to Fig. 3, but showing the ,t bar and hanger in the act of removalfl, 1g.l7 is a front elevation of the se ment art in section.

ly'pe-b iirs l are caused by key-levers 2 and bell-cranks 3 to swing up about ivots 4 to strike against the front side of a p aten 5; the ty e-bars being pivoted facewise or in any ot 101 suitable manner upon portions 6 of hangers 7 which are secured by radiating slots 8, formed in a segment 9, said ortions 6 dcpendim or ex tendin outwan ly and down from the segment. The slots or sockets 8 out completely through the bottom ed ,e of the segment as seen clearly at Fig. 5, an the hangers 7 are in the form of thin plates which fit snugly in the slots 8. Preferably the opposite cheeks or faces are parallel throughout, and in order to seat the some securely, a curved rod 10 is secured upon the rear sh c of the segment along its lower edge, and intersects the slotted portion of the segment. Said rod may be secured in any suitable nlanncr, as by thrusting it endwise in an undercut groove 11 formed in thelsegment. Each han er has in its lower portion a notch 12 formed on its rear edge to fit upon said seat-rod '10.

Pro'ecting from the top of each hanger is a shoul or 13 ads. ted to bear rearwardly against the front ace of the segment 9, said shoulder projecting above the slot 8. A finer-piece 14 may project forward from the body of the handle to be of use in extracting the same from the segment. The hangers are )rovided with individual locking devices, in this instance illustrated in the form of cocentrie cams 15 fitting in the slots 8 and ivotcd upon a common fulcrum rod 16, w 'ch may be mounted in any suitable manner upon the segment as by inserting the same endwise in an undercut groove 17 formed in the upper part of the slotted portion'or front. rib 18 of the segment. The hangers have bearings 19 to receive the eccentric rear edge of the cam, and each cam has a lever or handle portion 20 which normally stands upright or extends radially of the segment as seen at Figs. 1 and 7. In this position, the hanger is forced by the cam rearwardly and downwardly so that the shoulder 13 is pressed against the front face of the segment, and a notch 12 is pressed against the seat-rod 10, whereby'the hanger 1s fastened immovably in the segment.

To detach the type-bar, it is only necessary to swing the cam lever 20 down to the Fig. 3 position, which of course is done independently of other t 'pe-bars. The type-bar may then be ulled orwardly until the notch 12 1s clear 0 the seat-rod 10, and then the hanger and the type-bar may be drawn downwardly and forwardly, at Fig. 6, to remove the hanger from the segment; the typebar having an open ended slot 21 to on age a pin 22 on the bell-crank 3, whereby the detachment of the type-bar is facilitated. Each tvpe-bar has a heel 23 to press rearwardly t e usual universal bar 24, each hanger having a cutaway 25 to accommodate said universal bar.

Variations may be resorted to within the scope of the invention,
